<br />7.1.2.2 Sizing an Appropriate Facility
<br />Hypothetical transfer station dimensions and waste throughput quantities were developed based
<br />on a number of assumptions regarding the maximum daily waste acceptance rate, facility
<br />configuration, traffic flow patterns, and setbacks to the property line from the transfer station
<br />building footprint.
<br />
<br />Assuming MSW collection occurs 4 days per week, 52 weeks per year, the daily MSW
<br />throughput quantities for a Town-only facility range from 75 tons per day (tpd) in FY 2014-15 to
<br />approximately 100 tpd in FY 2033-34. Thus, a new transfer station anticipated to accommodate
<br />the Town-only MSW generation for the next 20 years should be sized to manage 100 tpd. Based
<br />on SCS's experience, a transfer station sized to handle 100 tpd of MSW would require a building
<br />footprint in the 10,000 square foot (sf) range, situated on a site pad of at least 2 acres within a
